浅析QR发动机动力性偏低原因及整改措施

从QR机型发动机台架实验动力性能与标定动力性能指标存在较大偏差的实际出发,分析了造成发动机动力性能偏低的主要原因,提出了整改方案,并做了进一步的台架实验验证,通过对实验数据的整理总结,从模具、加工、设计等方面,对影响发动机动力性能的相关零件进行了优化,最终完善了产品的动力性能。

The Analysis the Cause of QR Engine Low Dynamic Performance and Propose Corrective Measures

There is a big deviation starting from the QR model engine bench test the dynamic performance and calibration of dynamic performance,Analysised the main reason for the low engine power,Proposed rectification program,Rectification plans further validation of the bench,Through the collation of experimental data summary,Related parts of the QR models in engine performance is optimized included mold、machining、designing,Ultimately improve the dynamic performance of the product.
